Power Foods .......

Power Foods...
that boost your immunity
By Amanda MacMillan , Amanda MacMillan is a Prevention associate editor.

(Oct. 3, 2006) -- It takes more than an apple a day to keep viruses at bay. You can ensure your body and immunity run smoothly by getting your seven servings of fruits and veggies and 8 to 10 glasses of water a day, at the very least. The following ingredients can add extra flu-fighting punch to your winter meal plan.

Fish

Selenium, plentiful in shellfish such as oysters, lobsters, crabs, and clams, helps white blood cells produce cytokines--proteins that help clear flu viruses out of the body. Salmon, mackerel, and herring are rich in omega-3 fats, which reduce inflammation, increasing airflow and protecting lungs from colds and respiratory infections.

Your optimal dose Two servings a week (unless you're pregnant or planning to be).

Oats and Barley

These grains contain beta-glucan, a type of fiber with antimicrobial and antioxidant capabilities more potent than echinacea, reports a Norwegian study. When animals eat this compound, they're less likely to contract influenza, herpes, even anthrax; in humans, it boosts immunity, speeds wound healing, and may help antibiotics work better.

Your optimal dose At least one in your three daily servings of whole grains.

Garlic

Garlic contains the active ingredient allicin, which fights infection and bacteria. British researchers gave 146 people either a placebo or a garlic extract for 12 weeks; the garlic takers were two-thirds less likely to catch a cold. Other studies suggest that garlic lovers who chow more than six cloves a week have a 30% lower rate of colorectal cancer and a 50% lower rate of stomach cancer.

Your optimal dose Two raw cloves a day and add crushed garlic to your cooking several times a week.



Yogurt

Probiotics, or the "live active cultures" found in yogurt, are healthy bacteria that keep the gut and intestinal tract free of disease-causing germs. Although they're available in supplement form, a recent study from the University of Vienna in Austria found that a daily 7-ounce dose of yogurt was just as effective in boosting immunity as popping pills. In an 80-day Swedish study of 181 factory employees, those who drank a daily supplement of Lactobacillus reuteri--a specific probiotic that appears to stimulate white blood cells--took 33% fewer sick days than those given a placebo. Any yogurt with a Live and Active Cultures seal contains some beneficial bugs, but Stonyfield Farm is the only US brand that contains this specific strain.

Your optimal dose Two 6-ounce servings a day.

Chicken Soup

When University of Nebraska researchers tested 13 brands, they found that all but one (chicken-flavored ramen noodles) blocked the migration of inflammatory white cells--an important finding, because cold symptoms are a response to the cells' accumulation in the bronchial tubes. The amino acid cysteine, released from chicken during cooking, chemically resembles the bronchitis drug acetylcysteine, which may explain the results. The soup's salty broth keeps mucus thin the same way cough medicines do. Added spices, such as garlic and onions, can increase soup's immune-boosting power.

Your optimal dose Have a bowl when feeling crummy.

Tea

People who drank 5 cups a day of black tea for 2 weeks had 10 times more virus-fighting interferon in their blood than others who drank a placebo hot drink, in a Harvard study. The amino acid that's responsible for this immune boost, L-theanine, is abundant in both black and green tea--decaf versions have it, too.

Your optimal dose Several cups daily, all season; to get up to five times more antioxidants from your tea bags, bob them up and down while you brew.

10 Swine Flu Safety Dos and Don'ts

10 Swine Flu Safety Dos and Don'ts


Should you strap on a face mask, keep your kid off the schoolbus, or start an emergency food stash? Here, the panicky woman's guide to navigating the swine flu hype.
By Lauren Gelman

After a few days of non-stop swine flu coverage, many of us are starting to feel a bit panicky: Is this just media hype, or should we really be worried? Is there anything else I should be doing to keep my family safe? After all, when Vice President Joe Biden declares he's told his family to stop flying and avoid subways because of swine flu fears, why shouldn't you do it too?

To find out what's really worth the worry—and what's a waste of your time—we talked Dos and Don'ts with Myron S. Cohen, MD, director of the Institute of Global Health and Infectious Disease at UNC Chapel Hill. "Overall, it's about doing what makes you comfortable, as long as it's not crazy," he says. Here's what else he had to say:

DO:

Germ-proof your skin: Wash your hands well and often. Not every 10 minutes, but when it makes sense, like after using the bathroom, touching common objects at work—like the microwave or printer—or returning home from the grocery store. Use warm water and soap, and rub your hands together for about 20 seconds.

Pack Purell in your kid's backpack: The classic germ-killer can be 99% effective in 20 seconds, says Cohen. Slathering it on throughout the day can minimize the chance that your child will transmit potential germs on his hands to his mouth and nose, where the virus enters the body. Keep a bottle in your purse too.

Keep your distance. "Critical closeness—less than 6 to 10 feet—is required to catch airborne viruses," explains Cohen. That means avoiding close contact with people who are coughing or sneezing, but it doesn't mean you should hole up at home and never go out in public until the swine flu passes.

Call the doctor if you think it's flu. "Some people think everything that's an infection is the flu, but there's actually a very specific cluster of symptoms to worry about," he says. These include:

· Almost always: Fever, cough, muscle aches, and headaches
· Sometimes: Runny nose, red eyes, nausea and vomiting

Take the right meds: Antivirals like Tamiflu will only help if you actually have the flu. They're most effective in the first 2 days of illness onset, so if you have suspicious symptoms, call your doctor right away. Your doctor may also recommend a fever-reducer like Tylenol or an NSAID like ibuprofen for muscle pain relief.

Remember, never give aspirin to children or teens with the flu (or any virus); this can cause a rare but serious condition called Reye's Syndrome.

DON'T:

· Skip public transportation or cancel air travel: "I think this is going overboard for right now," says Cohen, despite VP Biden's advice to the contrary. "Remember, at this point only .0001% of the population has swine flu."

· Keep your kid out of school. Schools with individual cases are being closed. If you live in a community or state with no instances of swine flu, there's no need to keep your child home.

· Banish the schoolbus. Wondering whether it's safer to chauffeur your child to school yourself? Don't feel like you have to, says Cohen. "If it makes you feel more comfortable, there's no downside, but this not something I'd recommend yet."

· Stock up on face masks. The CDC has said they're not necessary for people who don't work in healthcare jobs, and Cohen agrees. "Wear a face mask if you have swine flu, so the virus is contained better. For the rest of us, you're much better off just focusing on hand washing and avoiding people who are visibly sick."

· Start an emergency food and water stash. "That is crazy, crazy, crazy," he says. "You have to be rational about this. There's no evidence that we are going to have influenza so vast and out of control that we have to shut down grocery stores. There is nothing to support this."

13 Facts About the Swine Flu

13 Facts About the Swine Flu
How to protect yourself and your family from the swine flu and what to do if you spot symptoms
By Lauren Gelman

On Sunday the government declared a public health emergency over swine flu, a strain of flu that normally occurs among pigs, but has begun spreading between humans. The virus, which originated in Mexico and, as of Monday afternoon, has infected more than 1,600 people worldwide, has also been detected in the US—with 50 cases reported to date—and Canada. Though the number of infected persons continues to climb, experts urge calm and caution.

While details are developing, not much is known yet about this flu strain, so understandably, questions arise: How contagious is this? Can your kids catch it at school? What do you do if you get sick and how do you know if it's the swine flu? Is pork safe to eat?

To help you separate fact from fiction (and fear!), Prevention turned to the CDC and public health experts for answers to your top questions. One reassuring fact right off the bat: Each of us can play a significant role in reducing our individual risk of infection, says Richard Besser, MD, acting director of the CDC. Here are the 13 top things you need to know about the swine flu.

Q: What is swine flu?
A: Just like humans, pigs can catch and spread the flu—a respiratory infection caused by a type of influenza A virus. Usually the virus is spread only among pigs, but sometimes humans can catch it too. This isn't the first time swine flu has struck: From December 2005 to February 2009, 12 cases were reported in the U.S.

Q: Is swine flu contagious?
A: Yes, the virus is contagious and has spread from person to person (rather than just from direct contact with an infected pig), but we currently don't know exactly how contagious it is, according to the CDC. The disease was first identified in Mexico, and currently 50 known cases have been identified in the U.S., in 5 states: New York, California, Ohio, Texas, and Kansas, says Besser. "But the more we look for it, the more cases we'll find," he says, noting that this isn't necessarily a sign that the disease is spreading, but just that we're able to correctly identify symptoms as swine flu.

Unlike the seasonal flu, which tends to most seriously affect the very young and very old, the age range of those affected in the U.S. so far is 7-54, says Besser, with a median age of 16. But this is likely to change as more cases are reported.

Q: How is swine flu spread?
A: Experts think this virus is spread the same way regular seasonal flu does—when an infected person coughs or sneezes and send the germs to other nearby people. Touching a surface that has been contaminated with the swine flu, such as a door handle or countertop, and then touching one's mouth, nose, or eyes can also transmit the virus.

Q: How dangerous is the swine flu?
A: So far, all cases in the U.S. have all been mild with only one hospitalization, and all patients have recovered, says Besser. But Mexican incidences have been more virulent, causing 152 deaths to date, as have past swine flu outbreaks in the US. A 1976 swine flu outbreak in Fort Dix, New Jersey, caused more than 200 cases, according to the CDC, including several serious illnesses and one death.

Q: What are symptoms of the swine flu?
A: Swine flu symptoms are similar to those of the regular flu: fever, cough, sore throat, body aches, headache, chills, and fatigue. Some people have reported more gastrointestinal-like symptoms, like diarrhea and vomiting. If you have any of these symptoms, talk to your doctor—in particular if you've recently traveled to Mexico, where the flu is believed to have originated. But remember that lots of viruses can have flu-like symptoms, including the common cold and seasonal allergies. "Just because it looks like the flu doesn't mean it is the flu," says Burke.

There are no symptoms unique to the swine flu, says Dr. Besser. The only way to know for sure is for your doctor to send a respiratory specimen for testing to a CDC-affiliated lab. With regular flu season in the U.S. winding down, swine flu symptoms may stand out more than they would have earlier in the year.

Q: How can I prevent myself or my family from catching swine flu?
A: The #1 thing you can do is be more vigilant about hand washing, says Donald Burke, MD, dean of the University of Pittsburgh Graduate School of Public Health. This is especially important after you've been in contact with other people (sick or healthy) or have used communal objects, such as the microwave at work. You'll only get sick if the virus actually enters your body, usually through your mouth or nose. Scrub your hands thoroughly with warm water and soap for at least 15-20 seconds to kill germs before they have the chance to invade. Other basic health hygiene rules from the CDC to follow include:
· Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it. Make sure your kids know to do the same.
· If you can't get to a sink to wash your hands, use an alcohol-based hand gel such as Purell to zap germs.
· Avoid contact with infected persons.
· If you get sick—with swine flu or anything else—stay home from work or school.

Another way to protect yourself: Regularly clean these 10 germiest zones in your home.

Q: Should I wear a face mask to protect myself?
A: "We would not recommend this as a precautionary measure," says Besser. Outside of healthcare settings where workers come into direct contact with infected people, the evidence for face masks reducing the spread of flu is not very strong, he explains. "I'd rather people focus on hand washing, or avoiding that little kiss of a greeting when you meet someone."

Q: Are there any medicines to prevent or treat swine flu?
A: Luckily, the current strains of swine flu are responsive to common antiviral drugs. These prescription medications, which keep flu viruses from reproducing in your body, can be used to treat people already infected with swine flu (they may make the illness milder, help you feel better faster, and reduce serious complications), as well as to prevent infection in high-risk people. If you think you may have flu symptoms or may have been exposed to someone diagnosed with swine flu, ask your doctor whether you should take these drugs, recommends Dr. Burke.

Keep in mind that influenza antiviral meds will only help if you're battling an influenza bug—they won't treat other types of viruses that may cause similar symptoms, according to the CDC. The best drugs for the current circulating strain of swine flu are Tamiflu (approved to treat and prevent flu in people age 1 and older) and Relenza (approved to treat infection in people age 7 and older and to prevent infection in people age 5 and older).

Q: Is there a vaccine for swine flu?
A: No, there is currently no vaccine for the swine flu and existing vaccines, like the flu shot you may have received earlier this year are not effective in preventing swine flu. But the CDC has taken steps to start a "seed stock" of the virus that could be used to make a vaccine in the future, although it is not ready to be manufactured yet.

Q: What if I have recently traveled to Mexico or have an upcoming trip planned?
A: The CDC just announced a new travel advisory for Mexico. "Out of an abundance of caution, all non-essential travel should be avoided for now," says Besser. If you've been to the country recently, there's no immediate action to take, other than just being on the lookout for flu-like symptoms and letting your doctor know if you experience them.

Q: Should I stop eating pork or other pig products?
A: No, says Besser. The swine flu cannot be spread through food. But it is important to make sure your meat is properly handled and cooked to reduce your risk of foodborne illness.

Q: What if I get the swine flu?
A: It's important to take care of yourself but equally important to take steps to avoid spreading the virus: Stay home from work or school, avoid crowds and public places, get plenty of rest, and take the full course of any medications your doctor prescribes. If you become sick and experience any of the following signs, the CDC recommends you seek emergency medical care:

Adults:
· Difficulty breathing or shortness of breath
· Pain or pressure in the chest or abdomen
· Sudden dizziness
· Confusion
· Severe or persistent vomiting

Children:
· Fast breathing or trouble breathing
· Bluish skin color
· Not drinking enough fluids
· Not waking up or interacting
· Being so irritable the child doesn't want to be held
· Flu-like symptoms improve but return with fever and worse cough
· Fever with a rash

Q: What are signs that this virus is spreading or slowing down?
A: "As we look around we will see more cases," cautions Besser. But if we see instances in Mexico decreasing, becoming less severe or people recovering sooner, that's a good sign.

Q: What if this becomes a flu pandemic?
A: It's the responsibility of the World Health Organization to officially declare a flu pandemic (an outbreak that is spread through populations over large regions or globally). A flu pandemic is defined in 6 phases; the WHO recently announced a change from stage 3 to stage 4, which means that there’s a new virus that’s starting to spread from human to human, but at smaller community levels. This means that a pandemic is more likely, but still not inevitable. However, the CDC has not drastically changed their current strategy in response to the level update. The government has already released 25% of the national stockpile of antiviral drugs—or about 11 million courses—to affected states. "This flu is evolving quickly, changing quickly," he says. "But we continue to approach this aggressively, and are taking bold action to minimize consequences."

Kiss Off Stress!

Kiss Off Stress
Ten ways to beat stress in 10 minutes or less
By: Alison KotchPublished: December 2008/January 2009 [ Updated: December 2008 ]

Did you know that the holiday season is the time of the year when you're most likely to die from a heart attack? According to research at the University of California, the deadliest day is Christmas, when you're 5 percent more likely to have a cardiac event. Of course, all the key stressors (finance, family, travel) seem destined to be worse this year (they always do). Since a restful night's sleep or an hour at the gym isn't always possible, here are 10 quick ways to stress less.

1 Second: Swear
Researchers at England's University of East Anglia Norwich looked into leadership styles and found that using swear words can reduce stress and boost camaraderie among coworkers. Good luck, shithead!

5 Seconds: Pop Fish Oil
According to research from the University of Pittsburgh, people with the highest blood levels of EPA and DHA omega-3 fatty acids are happier, less impulsive, and more agreeable. Try a daily supplement of 400 milligrams each of EPA and DHA fish oils.

10 Seconds: Eat Dark Chocolate
A study published in Proceedings of the National Academy of Sciences showed that the flavonoids in cocoa relax your body's blood vessels. Look for low-fat dark chocolate, which has more stress-busting flavonoids than milk chocolate.

30 Seconds: Know Your Hoku
Acupressure is a quick tension releaser, according to researchers at Hong Kong Polytechnic University who found it can reduce stress by up to 39 percent. For fast relief, massage your hoku (the fleshy part between the thumb and index finger) for 20 to 30 seconds. "This is the universal pressure point for easing upper-body tension," says Patrice Winter, a spokeswoman for the American Physical Therapy Association.

30 Seconds: Sit Back
Forget what you've been told about sitting up straight to relieve tension in your back. Researchers at the University of Alberta Hospital in Canada found that leaning back at a 135-degree angle is the best sitting position for alleviating back pain.

1 Minute: Add Garlic
Researchers at the University of Alabama at Birmingham believe they've figured out why garlic is good for heart health, and their finding implies it's a powerful stress buster too. When you digest garlic's main ingredient, organosulfur allicin, your body produces hydrogen sulfide, which relaxes blood vessels and increases blood flow.

3 Minutes: Brew Tea
In a study at University College in London, 75 men were given tea before completing two stressful tasks. Afterward, their cortisol levels dropped an average of 47 percent, compared with 27 percent for men who weren't given tea.

5 Minutes: Take a YouTube Timeout
Just the anticipation of laughing decreases the stress hormones dopac, cortisol, and epinephrine by 38, 39, and 70 percent, respectively, according to researchers at Loma Linda University in California. And when researchers at the University of Maryland showed short movie clips to study participants, those who watched funny films experienced a 22 percent increase in blood flow to their hearts.

8 Minutes: Budget Wisely
"Money is the biggest source of stress for a man during the holidays," says Bonnie Eaker Weil, PhD, author of Financial Infidelity. And with good reason: Men who avoid making budgets spend an average of 36 percent more on holiday gifts than those who don't, according to a 2002 survey. So go easy on your wallet and your heart. Sit down with your wife and quickly calculate how much you two want to spend on gifts this year.

10 Minutes: Just Do It
Kissing or hugging your wife can reduce stress because it raises levels of oxytocin, the hormone associated with bonding and love, say researchers at the University of North Carolina. And a Scottish researcher found that having sex regularly lowers anxiety, stress, and blood pressure.

The New Heart Risk

The New Heart Risk
The key to living free of heart disease and even cancer is to reduce chronic inflammation

By: Jayne Keedle; Illustration: Mario WagnerPublished: November 2008 [ Updated: November 2008 ]


Eat the rainbow to calm the fire in your arteries. Numerous studies have linked inflammation to heart disease, DNA damage, diabetes, and cancer, but scientists weren't sure which came first, the illness or the inflammation. When researchers at the University of California at San Diego School of Medicine recently discovered that inflammation causes diabetes, they answered the chicken-and-egg question and hatched a new metric to measure wellness. Some physicians now recommend that people monitor inflammation, just as they do cholesterol, and take an active approach to preventing it. "If you reduce inflammation, you reduce the risk of death from a heart attack," says Steven Nissen, MD, chairman of the Cleveland Clinic's department of cardiovascular medicine. Part of the body's immune response, acute inflammation is the swelling and pain you get when you stub your toe; it's a sign that the body is working to heal the injury. "But when inflammation becomes chronic, the acute system doesn't shut off," explains Mark Miller, PhD, professor of cardiovascular science and pediatrics at Albany Medical College. "What follows is a constant war between damage and inadequate repair." Here's how to crush inflammation.

Test Your Levels
Ask your doctor for a high-sensitivity C-reactive protein blood test. A CRP level of greater than 1 mg/L means you're at risk for cardiovascular disease; greater than 3 mg/L puts you in the high-risk category. Take the test twice, a month apart, to ensure an accurate score.

Trim Belly Fat
"The best way to reduce CRP levels is to lose even modest amounts of abdominal fat," says Dr. Nissen. Use your waist-to-hip ratio to assess your risk. Measure your waist in inches around the belly button and divide that number by your hip measurement. A number higher than 0.9 means slim down.

Ration Omegas
Experts recommend a 4:1 ratio of omega-6 fatty acids to omega-3s. But the typical American diet has 11 to 30 times more omega-6s (in saturated fats such as corn, soy, canola, and sunflower oils) than omega-3s. Doctors advise consuming 1.8 grams of omega-3s a day. That's the equivalent of eating two servings a week of fatty fish such as wild salmon or trout.

Eat the Rainbow
The flavonoids found in brightly colored fruits and vegetables reduce inflammation. The most potent choices are blueberries, purple grapes, cherries, oranges, and sweet potatoes. Eat seven servings a week. Gorge on FiberA high-fiber diet (25 to 35 grams a day) can reduce CRP levels by as much as 14 percent, according to a recent study. Boost your fiber intake by eating more beans (especially lentils and black beans) and whole grains. Buckwheat and amaranth are good choices because they have no gluten.

Choose Beef Over Chicken
Chicken is high in arachidonic acid, a fatty acid that prompts the body to produce inflammatory chemicals, so opt for beef instead, says nutritionist Monica Reinagel, author of The Inflammation Free Diet Plan. Beef tenderloin contains half as much arachidonic acid, plus higher levels of selenium and zinc, nutrients that fight inflammation. Grass-fed beef is the best, because it has a 2:1 omega-6 to omega-3 ratio. (Corn-fed cattle have a 4:1 ratio.)

Spice Things Up

Eating 2 to 4 grams of ginger a day suppresses the molecules in the body that promote inflammation. Recent studies suggest that it works at the DNA level, turning off the genes that trigger inflammation.

A Heart-Healthy Diet!

A Heart-Healthy Diet: Wining and Dining the Heart


By Katherine KamWebMD Feature
Reviewed by Brunilda Nazario, MD


Wine and chocolate conjure up images of the good life, but they may also be part of a heart-healthy diet.

Given the high rates of heart disease among Americans, researchers have taken a close look at numerous foods and supplements -- from fatty fish to vitamin E -- to analyze the ideal ingredients for a heart-healthy diet.


"I don't think it's out of the realm of possibility that we will ultimately find some magic food that's really going to make a difference," says Alice Lichtenstein, DSc, professor of nutrition science and policy at the Friedman School of Nutrition at Tufts University in Boston.


But she cautions against a false sense of security. For instance, pouring a fish oil capsule over your hot fudge sundae won't protect your heart, she says. It's still best to follow a heart-healthy diet and lifestyle. That means nutritious eating, as well as maintaining a healthy weight, controlling blood pressure and cholesterol, avoiding smoking, and staying physically active.


"We've had high hopes for individual foods for a long time, but also, we're going to have to bite the bullet," she tells WebMD.


So keep hitting the gym -- and reward yourself afterward with a glass of red wine or a piece of chocolate.


Red Wine and the Heart-Healthy Diet

Does drinking red wine reduce the risk of heart disease? Some studies have shown that people who drink moderate amounts of alcohol have less heart disease risk than nondrinkers, and some research suggests that red wine may offer extra health benefits. It contains compounds, such as flavonoids and resveratrol, that may help to limit atherosclerosis, or hardening of the arteries.


Drinking alcohol regularly, including red wine, may boost levels of "good" HDL cholesterol. One to two drinks per day have been shown to increase HDL by about 12%, according to the American Heart Association. The extra HDL can help to remove bad "LDL" cholesterol, meaning that there's less of the material to contribute to fatty plaques inside arteries. Moderate alcohol consumption may also reduce the risk of blood clots.


If you drink wine or alcohol, the American Heart Association urges moderation: no more than two drinks per day for men and one for women.


And if you don't drink alcohol, the AHA warns against starting in order to prevent heart disease, especially when you can take so many other preventive measures. Drinking alcohol increases the risk of addiction, high blood pressure, obesity, breast cancer, and accidents.


Chocolate and the Heart-Healthy Diet

Dark chocolate and cocoa are rich in antioxidants called flavonoids. Research suggests that eating flavonoid-rich chocolate helps to keep blood vessels healthier by improving their ability to expand.

One small study showed that eating high-flavonoid dark chocolate daily helped high blood pressure patients lower their blood pressure and reduce LDL. Patients who ate white chocolate got no beneficial effects.

Eating chocolate in moderation is fine, Lichtenstein says. But be aware that flavonoid levels differ in various chocolate products, so there's no guarantee that you'll get a dose large enough for health benefits. Also, too much chocolate has no place in a heart-healthy diet because the extra calories can lead to weight gain.


Fish Oil and the Heart-Healthy Diet

Eating fish rich in omega-3 fatty acids may help prevent heart disease. Good choices include fatty fish such as salmon, lake trout, mackerel, sardines, and albacore tuna, according to the AHA.


Fish oil contains docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Lichenstein has reviewed many studies on fish oil and cardiovascular disease, and most of the evidence associates DHA and EPA with decreased risk of cardiovascular disease, she says. People who report eating two or more servings of fish per week have a lower risk, she adds.


How do omega-3 fatty acids help to promote heart health? Experts don't know for sure. "It's still open to debate," Lichenstein says.


But whatever the reason, there is evidence that omega-3 fatty acids cut risk of death, heart attack, and dangerous heart rhythms in people with cardiovascular disease, according to the NIH. Omega-3 fatty acids also lower "bad" LDL levels, mildly decrease blood pressure, and lower levels of a blood fat called triglycerides.


Getting omega-3 fatty acids from food is best, the AHA says. It recommends at least two servings of fish per week. But people with coronary artery disease or high triglycerides may want to talk to their doctor about taking a supplement if they're not getting enough omega-3 fatty acids in their diet.


Cholesterol-Lowering Foods and the Heart-Healthy Diet

Cholesterol-lowering margarines that contain plant sterols have been shown to decrease "bad" LDL cholesterol levels. Other foods that are sterol-fortified include some orange juices, chocolate bars, yogurt, and more.


Though these cholesterol-lowering products seem to be effective, they should be part of a comprehensive heart-healthy diet, one that is low in saturated fat and cholesterol, experts say.


Fruits, Vegetables, and the Heart-Healthy Diet

Many people take antioxidant supplements, such as vitamin E, vitamin C, and beta-carotene, to prevent heart disease, but there's no proof that dietary supplements help, experts tell WebMD.


"We've been very disappointed with supplements in general, especially with respect to cardiovascular disease, in the past three or four years," says Lichtenstein, who co-wrote the AHA's scientific advisory on antioxidant vitamin supplements and cardiovascular disease.


"All the major vitamin E intervention studies have shown no significant effects," she adds. Many people take vitamin E on the widely held belief that it may help prevent or delay heart disease.


Instead of relying on diet supplements, you should follow a heart-healthy diet, Lichtenstein says. "We know that diets high in fruits and vegetables are associated with decreased risk of cardiovascular disease and cancer."


Why the benefit? It could be substances in the fruits and vegetables themselves. Or people who eat a lot of fruits and vegetables may be eating fewer unhealthy foods, or perhaps they're more likely to exercise and not smoke, Lichtenstein says.


To make sure you eat a wide variety of foods, aim for "a rainbow of fruits and veggies," says Judith Levine, RD, MS, a registered dietitian with the American Heart Association's San Francisco office. Some examples:

· Red: watermelon, red grapes, strawberries, cranberries, tomatoes, apples, beets

· Orange/Yellow: carrots, sweet potatoes, oranges, tangerines, lemons, apricots, cantaloupe, butternut squash

· Green: spinach, kale, collard greens, lettuce, broccoli, asparagus, artichokes, Brussels sprouts

· Blue/Purple: purple cabbage, eggplant, raisins, figs, blackberries, blueberries, purple grapes, plums, prunes

And while experts say that some stress is good for you -- it can sharpen your senses and your mind -- too much stress is bad for your mental and physical health. At the same time, relaxation can do wonders to restore balance in your life -- and may even reduce some of the health risks associated with stress.

WebMD talked to the experts to learn more about relaxation -- and how to attain it. What follows are 10 on-the-spot techniques you can use -- any time and almost anywhere -- to reduce the tension in your life.


1. Meditate
If you're thinking meditation means twisting your body into an uncomfortable position and uttering "oohs" and "omms" for an hour, guess again. Any repetitive action can be a source of meditation, says Herbert Benson, MD, author of The Relaxation Response anddirector emeritus, Benson-Henry Institute for Mind Body Medicine in Chestnut Hill, Massachusetts. This includes walking, swimming, painting, knitting -- any activity that helps keep your attention calmly in the present moment.

When you catch yourself thinking about your job, your relationship or your lifelong to-do list, experts say to simply let the thought escape, and bring your mind back the repetition of the activity. Try it for just 5 to 10 minutes a day and watch stress levels drop.


2. Picture Yourself Relaxed
Is your mind too talkative to meditate? Try creating a peaceful visualization, or "dreamscape." To start, simply visualize anything that keeps your thoughts away from current tensions. It could be a favorite vacation spot, a fantasy island, that penthouse in New York City -- or something "touchable," like the feel of your favorite silk robe or cozy sweater.

The idea is to take your mind off your stress, and replace it with an image that evokes a sense of calm. The more realistic your daydream -- in terms of colors, sights, sounds; even touch and feel -- the more relaxation you'll experience.


3. Breathe Deeply
Feeling stressed evokes tense, shallow breathing, while calm is associated with relaxed breathing, says Michael Lee, author of Turn Stress into Bliss and founder of Phoenix Rising Yoga Therapy in Bristol, Vermont. So to turn tension into relaxation, he says, change the way you breathe.

Try this: Let out a big sigh, dropping your chest, and exhaling through gently pursed lips, says Joan Borysenko, PhD, director of Harvard's Mind-Body Clinical Programs. Now imagine your low belly, or center, as a deep, powerful place. Feel your breath coming and going as your mind stays focused there. Inhale, feeling your entire belly, sides and lower back expand. Exhale, sighing again as you drop your chest, and feeling your belly, back and sides contract. Repeat 10 times, relaxing more fully each time.


4. Look Around You
"Mindfulness is the here-and-now approach to living that makes daily life richer and more meaningful," says Claire Michaels Wheeler, MD, PhD, author of 10 Simple Solutions to Stress. It's approaching life like a child, without passing judgment on what occurs. Mindfulness means focusing on one activity at a time, so forget multi-tasking! Staying in the present-tense can help promote relaxation and provide a buffer against anxiety and depression.

Practice it by focusing on your immediate surroundings. If you're outdoors, enjoy the shape and colors of flowers, hear a bird's call or consider a tree. In the mall, look at the details of a dress in the window, examine a piece of jewelry and focus on how it's made, or window-shop for furniture, checking out every detail of pattern and style. As long as you can keep your mind focused on something in the present, stress will take a back seat.


5. Drink Hot Tea
If you're a coffee-guzzler, consider going green. Coffee raises levels of the notorious stress hormone, cortisol, while green tea offers health and beauty, says Nicholas Perricone, MD, author of 7 Secrets to Beauty, Health, and Longevity.

Chamomile tea is a traditional favorite for calming the mind and reducing stress. And black tea may be a stress-fighter, too, researchers from University College London report. Participants who drank regular black tea displayed lower levels of cortisol, and reported feeling calmer during six weeks of stressful situations than those who drank a placebo with the same amount of caffeine.


6. Show Some Love
Induce the relaxation response by cuddling your pet, giving an unexpected hug to a friend or family member, snuggling with your spouse, or talking to a friend about the good things in your lives, says psychologist Deborah Rozman, PhD, co-author of Transforming Stress. When you do, you'll be reducing your stress levels.

Why? Experts say social interaction helps your brain think better, encouraging you to see new solutions to situations that once seemed impossible, she says. Studies have also shown that physical contact -- like petting your dog or cat -- may actually help lower blood pressure and decrease stress hormones.


7. Try Self-Massage
When your muscles are tense and you've no time to visit a pro, try this simple self-massage technique from Darrin Zeer, author of Lover's Massage and Office Yoga. Relax, and travel straight to Zen-land.
· Place both hands on your shoulders and neck.
· Squeeze with your fingers and palms.
· Rub vigorously, keeping shoulders relaxed.
· Wrap one hand around the other forearm.
· Squeeze the muscles with thumb and fingers.
· Move up and down from your elbow to fingertips and back again.
· Repeat with other arm.


8. Take a Time-Out
Adults need time-outs, too. So when you sense your temper is about to erupt, Jeff Brantley, MD, author of Five Good Minutes In the Evening, suggests finding a quiet place to sit or lie down and put the stressful situation on hold. Take a few deep breaths and concentrate on releasing tension and calming your heartbeat. Quiet your mind and remember: Time is always on your side, so relax. The stress can wait.


9. Try a Musical Detour
Music can calm the heartbeat and soothe the soul, the experts say. So, when the going gets rough, take a musical stress detour by aligning your heartbeat with the slow tempo of a relaxing song. And you might want to make that a classical tune. Research shows that listening to 30 minutes of classical music may produce calming effects equivalent to taking 10 mg of Valium.


10. Take an Attitude Break
Thirty seconds is enough time to shift your heart's rhythm from stressed to relaxed, Rozman says. The way to do that: Engage your heart and your mind in positive thinking. Start by envisioning anything that triggers a positive feeling -- a vision of your child or spouse, the image of your pet, that great piece of jewelry you're saving up to buy, a memento from a vacation -- whatever it is, conjuring up the thought will help slow breathing, relax tense muscles and put a smile on your face. Rozman says that creating a positive emotional attitude can also calm and steady your heart rhythm, contributing to feelings of relaxation and peace.

Health Benefits of Tai Chi and Qigong.

Health Benefits of Tai Chi and Qigong.

Tai chi and qigong are two mind-body practices that originated in ancient China. Practiced widely in China for thousands of years, both tai chi and qigong have become popular in the West. This might be because people of almost any age or condition can learn them.

Large, clinical studies on the health benefits of tai chi and qigong are lacking. But many who practice tai chi and qigong report heightened feelings of well-being along with a variety of other health benefits. A few studies are beginning to support some of these claims.

What is tai chi?
Tai chi is a type of low-impact, weight-bearing, and aerobic -- yet relaxing -- exercise. It began as a martial art. As it developed, it took on the purpose of enhancing physical and mental health. Practiced in a variety of styles, tai chi involves slow, gentle movements, deep breathing, and meditation. The meditation is sometimes called “moving meditation.”

Some people believe that tai chi improves the flow of energy through the body, leading to better wellness and a wide range of potential benefits. Those benefits include:
· Improved strength, conditioning, coordination, and flexibility
· Reduced pain and stiffness
· Better balance and lower risk of falls
· Enhanced sleep
· Greater awareness, calmness, and overall sense of well being

What are the health benefits of tai chi?
Because of the gentle nature of tai chi, researchers are particularly interested in the potential tai chi has of providing benefits for older adults. The National Center for Complementary and Alternative Medicine (NCCAM) and other agencies are funding a variety of tai chi research studies. Some of the findings from these studies suggest a wide range of benefits. Overall results, though, have been mixed, and more research is needed to confirm the health claims that are being made.

Here are some examples of the kind of results that have encouraged researchers:
· Balance and strength. The Oregon Research Institute found that, after six months, tai chi participants were twice as likely to have no trouble performing moderate to rigorous activities as nonparticipants. The benefit was greatest among those who started with the poorest health or worst function. Other studies have shown a reduction in falls among tai chi participants. In the 1990s, two studies sponsored by the National Institute on Aging (NIA) found that tai chi exercises cut the fear of falling and risk of falls among older people. Two small sports medicine studies suggest that tai chi may improve sensitivity to nerve signals in ankles and knees, which might prevent falls. But an evidence-based review of many studies only confirmed better balance -- not a reduction in falls.
· Osteoarthritis. Patients with osteoarthritis assigned to a tai chi group during a three-month study reported less joint pain and stiffness than when they started. They also had less pain and stiffness than patients in a control group.
· Sleep. Exploring tai chi’s impact on sleep, the Oregon researchers found that tai chi participants had improved sleep quality and length. They also had fewer sleep disturbances than people in a low-impact exercise group. A UCLA study of tai chi chih, a Westernized version of tai chi, also supports claims of sleep benefits. The benefits are similar to those gained through drugs or cognitive behavioral therapy. Two-thirds of the people practicing tai chi chih had major improvements in sleep quality, compared with one-third who of those involved in health education sessions.
· Shingles. A viral disease that causes a painful skin rash and blisters, shingles is caused by the same virus that causes chickenpox. In a shingles study supported by the NIA and NCCAM, researchers found that tai chi prompted an immune response to the varicella-zoster virus similar to that prompted by the varicella vaccine. When combined with the vaccine, tai chi helped create even greater levels of immunity -- double those of the control group. Tai chi participants also reported improvements in function, pain, vitality, and mental health.

What is qigong?
Qigong -- pronounced chee gong -- is a practice that involves a series of postures and exercises -- including slow, circular movements -- regulated breathing, focused meditation, and self-massage.

There is a variety of styles, and they are classified as martial, medical, or spiritual. Some qigong styles are gentler like tai chi and can easily be adapted. Others are more vigorous like kung fu.

One unique feature of qigong is its ability to train the mind to direct the body’s energy, or chi, to any part of the body. Some believe that, when moved correctly, chi can bring your body to a natural state of balance. Qigong is believed to relax the mind, muscles, tendons, joints, and inner organs -- helping to improve circulation, relieve stress and pain, and restore health.

As with tai chi, a variety of benefits have been linked to qigong. They include:
· Greater stamina and vitality
· Reduced stress
· Enhanced immune system
· Improved cardiovascular, respiratory, circulatory, lymphatic, and digestive function
· Lower blood pressure
· Less risk of falling
Practiced widely in the clinics and hospitals of China, qigong may have broad health benefits. However, most of the studies conducted on qigong are limited in scope. Many are small case studies conducted in China -- not large, randomized, controlled trials reported in peer-reviewed English-language journals.

What are the health benefits of qigong?
Some believe that as a complement to Western medicine, qigong can help the body heal itself, retarding or even reversing the effects of certain diseases linked to aging. Here are a few examples of findings from small studies showing qigong benefits:

· High blood pressure. In a study lasting 20 years, patients with hypertension -- whether in the control or qigong group -- were given drugs to control blood pressure. At first, participants in both groups had a drop in blood pressure. But blood pressure in the qigong group stabilized over time. They even were able to lower their use of blood pressure drugs. By contrast, the control group had an increase in blood pressure, requiring greater use of drugs.

· Immune system. Just 30 minutes of daily qigong training for one month might produce a tangible impact on the body’s immune system. In one study, blood samples taken the day before training started and after it was completed showed a statistically significant difference in white blood cell counts.

· Stroke. In one study looking atmortality, among patients who’d suffered a stroke, 86 in the qigong group survived compared with 68 in the control group. That was after a period of 30 years. Compared to the control group, patients practicing qigong had a 50% reduction in death from any cause, death from stroke, and sickness related to stroke. However, it’s not clear if the qigong participants were already healthier, making them more likely to live longer.

· Fibromyalgia. One small pilot study showed fewer symptoms and improvement in function among patients with fibromyalgia who were practicing qigong. Fibromyalgia is a chronic condition that can cause widespread pain and fatigue. Larger trials are needed to confirm the results.

Are there any special precautions for tai chi or qigong?
Both tai chi and qigong are gentle exercises with few risks. However, if you are older, have a health condition, or have not exercised in a long time, tell your health care provider if you want to try either of these practices. Think of both as complements to Western medicine, and not replacements for it.

In general, use caution if you are pregnant or if you have a joint problem or severe osteoporosis. It is best to not do tai chi or qigong right after eating, if you are very tired, or if you have an active infection.

Eat, Exercise, Relax and Sleep Your Way to Better Sex

Eat, Exercise, Relax, and Sleep Your Way to Better Sex

Better sex doesn't just involve technique. Keeping a fit mind and body can increase your enjoyment of bedroom antics.
By Dulce ZamoraWebMD Weight Loss Clinic-Feature

Thought about leading a healthier lifestyle but haven't gotten around to doing it? Here's a possible incentive: Experts say people who are mentally and physically fit are more likely to have good sex lives.

· Can food put you in the mood?
· A few more tips on giving your libido a lift
· Sleep: Enhances sex and weight loss?
"If you feel good about yourself, you are in a better position to feel good about relationships, including your sex life," says Karen Zager, PhD, a psychologist in private practice in New York City.

"When one is not feeling well, and is exhausted, it can certainly have a negative impact on the quality of one's sex life," says Saralyn Mark, MD, a senior medical adviser at the Office on Women's Health.

This may all seem intuitive, yet many people find the road to a fitter mind and body to be bumpy, especially if it involves losing weight, starting an exercise program, reducing stress, or getting enough sleep.

One big reward, though, is to look and feel better -- arguably a plus for good romantic and sensual activities.

Eat Right
While there is no proven connection between a balanced diet and bedroom performance, a poor diet can cause health problems that can possibly interfere with sex.

Studies show animals that get too few calories tend to have weakened immune systems, says John Allred, PhD, professor emeritus of nutrition at Ohio State University. He says illness can be a big hurdle for pleasurable intercourse.

"If you have heart disease, then you might be taking medication that would inhibit sexual activity, or you might be afraid to have a heart attack," says Allred. "If you have the flu, a high fever, or just don't feel good ... any of these things would be a turn-off."

Mark Kantor, PhD, associate professor of nutrition and food science at the University of Maryland, agrees, saying, "You will feel sexy if you look and feel good."

A way to do that is to eat an overall balanced diet and to exercise each day. The two go hand-in-hand, says Kantor, as demonstrated by today's obesity problem, in which people eat too much food and aren't active enough.

Move That Body
Being physically active can be a natural Viagra boost, according to the American Council on Exercise (ACE), which recommends 20 to 30 minutes of moderate exertion a day.

"Men and women who exercise regularly are going to have increased levels of desire," says Cedric Bryant, PhD, ACE's chief exercise physiologist. "They're going to have enhanced confidence, enhanced ability to achieve orgasm, and greater sexual satisfaction."

If that isn't motivation enough to work out, consider this: Researchers have found that there is a correlation between waist size and a man's odds of having erectile dysfunction (ED). The larger the man's waist size, the greater his chance of having ED (because of a higher risk of underlying cardiovascular disease).

Need more positive reinforcement? Studies show that regular, moderate exercise can have a positive benefit on major sexual problems, such as ED in men and low libido in both men and women.

It only makes sense, say experts, since ED is often caused by poor blood flow to the penis, and exercise can improve the body's ability to pump and circulate blood throughout the body.

The same can be true for the ladies. In one University of Texas at Austin study, physically active women who watched an X-rated film had a 169% greater blood flow to the vagina compared with when they were inactive.

And there's more good news. Mark says exercise can promote the body's release of hormones important for sexual arousal, increase aerobic capacity and muscle strength, and boost self-body image -- all definite benefits for between-the-sheets play.

Sweet Dreams
For many of us, a good roll in the sack requires energy and the right mood -- elements that can be compromised when we are sleepy or tired.

While there is no direct relationship between slumber and better sex, a National Sleep Foundation (NSF) poll, conducted in 2002, shows people's moods can be affected by the amount of shut-eye they get.

People who sleep less than six hours are more likely to report they are tired, stressed, sad, and angry than those who sleep more than eight hours. On the other hand, those with few sleep problems tend to report they are "full of energy," "relaxed," and "happy."

In his practice, Russell Rosenberg, PhD, director of the Northside Hospital Sleep Medicine Institute in Atlanta, says chronic sleep-loss patients report not only being too physically tired for sex, but also having decreased libido.

Unfortunately, lower sex drive, tiredness, and grouchiness are the least of worries with sleep deprivation. Research shows people who don't catch enough winks tend to:
· Get into more accidents. Inadequate sleep affects perception and motor skills.
· Find it harder to lose weight. Not enough shut-eye can affect the body's ability to metabolize carbohydrates.
· Have an increased chance of a hormonal or metabolic disorder, which can indirectly put you at risk for medical problems such as type II diabetes and heart disease.

All of these consequences could undoubtedly put a damper on a person's sex life.

Rosenberg recommends trying to increase your total sleep time, even if it's just adding a half-hour or more per week. "Try it, and see how it affects your sex life," he says.

Relax
The brain may be the most important sex organ of all. It is perhaps in the mind where beliefs take hold and flourish about the effects of certain foods on sexual prowess, even as scientists deny any direct connection between diet and erotic fitness.

It is in the mind that people feel self-confident when they like the effects of exercise on their bodies. It is also where they feel happy and energized once they've gotten enough sleep.

Yet the inner workings of the brain can also keep a person from focusing on the delights of bedroom actions.

"In order to have a really healthy and pleasurable sex life, you have to be able to dismiss work; you have to be able to unwind and experience pleasure," says Zager. She says this means being able to temporarily forget about what your boss said, what was in the memo, what bills need to be paid, and what the children need.

Sex requires relaxation and time, adds Zager, noting that some couples may be too stressed and busy to enjoy or even have intercourse. She suggests setting priorities.
"Just how important is sex to you and your partner?" asks Zager. If it is vital to your relationship, she advises finding a way to work it into your schedule and working on making yourself less stressed or tired.

Some recommendations include eliminating some activities from your busy life, delegating jobs to someone else (by giving it to a partner, or hiring someone to do it), and doing an across-the-board cut in time spent on each activity.

To unwind, Zager suggests taking 5 to 30 minutes either to walk, meditate, take a hot bath, do yoga, or sit by yourself. This time can help charge personal batteries and can help make transitions between your work, family, and sex life.

To Your Bedroom Health
Living healthy may, indeed, have its benefits. If you eat a balanced diet, exercise regularly, sleep enough, and take time to relax, there's a good chance your life between the sheets will improve.

Of course, there is no guarantee. But, as Zager says, it all forms a really good foundation.

"If you've got a good foundation of stress management, and setting your priorities, and taking good care of yourself, then on top of that, you can build relationships with other people and an enjoyable sex life," she says.

Healthy Aging - Sexual Vitality

Healthy Aging - Sexual Vitality

Because sexuality tends to be a private matter, it's likely that you've heard less about sexual change than any other element of aging. Fortunately, the news is good-for most healthy adults, pleasure and interest don't diminish with age. Most people are sexual throughout their lives, with or without a partner, and some feel greater sexual freedom in their later years. On the other hand, some men and women are content to be sexually inactive.

Around age 50, men and women typically begin to notice changes in their sexual drive, sexual response, or both. Like so many other physical changes that evolve over time, these aren't signs that you are losing your sexuality. Rather, these changes are simply something to adjust to and discuss openly with your partner and/or your doctor.


Normal sexual changes in men !

As you age beyond your 50s, you may find that:
· Male sex drive is minimally affected by age (although health problems, certain medicines, or relationship stress can lower sex drive).
· Erections become less firm and tend to take more time than when you were younger.
· You may be able to delay ejaculation for longer than when you were younger.


Normal sexual changes in women !

After menopause, estrogen and androgen levels drop, causing physical changes. You may find that:
· It can take longer to become sexually excited.
· Your skin may be more sensitive and easily irritated when caressed.
· Intercourse may be painful because of thinning vaginal walls (regular sex often helps prevent this from becoming severe). If a water-based lubricant (such as Astroglide or Replens) isn't enough, talk to your doctor about vaginal estrogen cream, which reverses thinning and sensitivity. For more information, see the topic Menopause and Perimenopause.
· You are less interested in sex.

If you have noticed sexual changes that don't seem to be linked to normal aging, talk to your doctor. There are a number of medicines that can cause sexual problems, as well as health conditions that can cause sexual problems.



Adjusting to age-related sexual changes.

With a little experimentation and patience, you can adjust to sexual changes and satisfy your sexual and intimacy needs. If you think your sexual interest might be affected by a medicine or health problem, work with your doctor to correct or treat it. Talk with your partner about any misgivings you might have so you can handle them together.

With your partner, take your time to set a relaxed mood and engage in foreplay. Use a lubricant if vaginal dryness or irritation is a barrier to enjoying sex. If you drink alcohol, remember that a small amount may relax you and increase your responsiveness, but too much alcohol is not likely to be helpful.

Sexually transmitted diseases (STDs) are a risk no matter what age you are. Unless you and your partner have recently been tested or you are 100% sure that you both have been monogamous for many years without infection, make sure that you practice safe sex to prevent STDs.

1. Lose weight. Get your BMI (body mass index, a measurement of weight in relation to height) into the range of 18.5-24.9, and you will be doing your heart and blood pressure a favor. Think of it this way: Extra weight you carry around is like bricks in a backpack, putting pressure on every part of your body.

2. Eat plenty of whole grains. Have seven to eight servings per day of grains and grain products (these can include breakfast cereal, whole grain bread, rice, pasta, etc.)

3. Eat plenty of fruits and vegetables. Having at least eight to 10 servings of a variety of colorful fruits and vegetables will ensure you get all the healthy antioxidants, vitamins, minerals, and fiber you need.

4. Dairy up. Consuming two to three servings daily of low-fat or nonfat diary foods will also help build strong bones and teeth, and enhance weight loss.

5. Limit meat, fish, and poultry to two servings a day. Move the meat off the center of your plate, and enjoy more grains and produce. When you do have meats, fish, and poultry, always chose lean varieties.

6. Go nuts. Incorporate four to five servings a week of nuts, seeds, and legumes into your diet. They provide plenty of protein and healthful fats.

7. Limit fats and oil to two to three servings per day. Fats are the most concentrated source of calories. Limiting them will help you control your weight.

8. Hold the salt. Limit your sodium intake to approximately 2,400 milligrams a day (a moderate level). This means eating fewer canned and processed foods, and more fresh foods.

9. Get off the couch. Exercising at least 30 minutes per day can significantly reduce blood pressure. Any form of physical activity, done most days of the week, will do the trick.

10. Drink in moderation. If you do it at all time, but limit yourself to two drinks per day.

Antioxidants and Your Immune System: ..........

Antioxidants and Your Immune System: Super Foods for Optimal Health

One of the best ways to keep your immune system strong and prevent colds and flu might surprise you: Shop your supermarket’s produce aisle.
Experts say a diet rich in fruits and vegetables can help you ward off infections like colds and flu. That’s because these super foods contain immune-boosting antioxidants.
What are antioxidants? They are vitamins, minerals, and other nutrients that protect and repair cells from damage caused by free radicals. Many experts believe this damage plays a part in a number of chronic diseases, including hardening of the arteries (atherosclerosis), cancer, and arthritis. Free radicals can also interfere with your immune system. So fighting off damage with antioxidants helps keep your immune system strong, making you better able to ward off colds, flu, and other infections.

Antioxidants for Immunity: Where to Find Them

Adding more fruit and vegetables of any kind to your diet will improve your health. But some foods are higher in antioxidants than others. The three major antioxidant vitamins are beta-carotene, vitamin C, and vitamin E. You’ll find them in colorful fruits and vegetables – especially those with purple, blue, red, orange, and yellow hues. To get the biggest benefits of antioxidants, eat these foods raw or lightly steamed; don’t overcook or boil.
Beta-carotene and other carotenoids: Apricots, asparagus, beets, broccoli, cantaloupe, carrots, corn, green peppers, kale, mangoes, turnip and collard greens, nectarines, peaches, pink grapefruit, pumpkin, squash, spinach, sweet potato, tangerines, tomatoes, and watermelon.
Vitamin C: Berries, broccoli, Brussels sprouts, cantaloupe, cauliflower, grapefruit, honeydew, kale, kiwi, mangoes, nectarines, orange, papaya, red, green or yellow peppers, snow peas, sweet potato, strawberries, and tomatoes.
Vitamin E: Broccoli, carrots, chard, mustard and turnip greens, mangoes, nuts, papaya, pumpkin, red peppers, spinach, and sunflower seeds.
Other super foods that are rich in antioxidants include:
· Prunes
· Apples
· Raisins
· All berries
· Plums
· Red grapes
· Alfalfa sprouts
· Onions
· Eggplant
· Beans


Vitamins aren’t the only antioxidants in food. Other antioxidants that may help boost immunity include
· Zinc: Found in oysters, red meat, poultry, beans, nuts, seafood, whole grains, fortified cereals, and dairy products
· Selenium: Found in Brazil nuts, tuna, beef, poultry and fortified breads, and other grain products

Antioxidant Super Foods: How Much Do You Need?

For optimal health and immune functioning, you should eat the recommended dietary allowance (RDA) of the antioxidant vitamins and minerals. That’s the amount of a vitamin or nutrient that you need to stay healthy and avoid a deficiency.
Here are the RDAs for some antioxidants:
Zinc: 11 milligrams for men, 8 milligrams for women.
Selenium: 55 micrograms for men or women. If you are vegetarian, you may need to eat as much as 50% more. That’s because your body absorbs less zinc from plant foods.
Beta-carotene: There is no RDA for beta-carotene. But the Institute of Medicine says that if you get 3 milligrams to 6 milligrams of beta-carotene daily, your body will have the levels that may lower risk of chronic diseases.
Vitamin C: 90 milligrams for men, 75 milligrams for women. Smokers should get extra vitamin C: 125 milligrams for men and 110 milligrams for women.
Vitamin E: 15 milligrams for men and women.

How Foods Boost Immunity

Can’t you get antioxidants from taking a vitamin or a supplement? Yes, but you may be missing out on other nutrients that could strengthen the immune system. Foods contain many different nutrients that work together to promote health. For example, researchers delving into the mysteries of fruits and vegetables and the complex antioxidants they contain have discovered benefits of:
· Quercetin: a plant-based chemical (phytochemical) found in apples, onions, teas, red wines, and other foods. It fights inflammation and may help reduce allergies.
· Luteolin: a flavonoid found in abundance in celery and green peppers. It also fights inflammation and one study showed it may help protect against inflammatory brain conditions like Alzheimer’s.
· Catechins: a type of flavonoid found in tea. Catechins in tea may help reduce risk of heart disease, cancer, and Alzheimer’s disease.
If you can’t get enough antioxidants in your diet by eating fresh produce, some experts recommend taking a multivitamin that contains minerals, too. But be cautious about taking individual immune system supplements to boost immunity. With antioxidants, as with most anything, moderation is best. Vitamins A and E, for example, are stored in the body and eliminated slowly. Getting too much can be toxic.
